As the Universe has expanded, the **temperature** of the Cosmic Microwave Background radiation has dropped. Initially, the universe was very hot after the Big Bang, but as it expanded, the temperature decreased. Thus, the correct answer is **c) Temperature**.
While the volume of the Universe has indeed increased, the question specifically mentions something that has dropped, which points to temperature as the correct answer.
